Askin's Tumor with Massive Hemoptysis.

Askin's tumor is a rare neoplasm of the chest wall with a dismal prognosis and is usually observed in young subjects. We describe a 15-year-old female with massive hemoptysis who had an extensive thoracopulmonary tumor on chest CT. She underwent bronchoscopy which showed the location of the tumor in the bronchus intermedius. The biopsy obtained from the tumor enabled a diagnosis of Askin's tumor to be made. After induction of chemotherapy, hemoptysis stopped and her constitutional symptoms improved. We focus on the clinical features, imaging, and histopathological characteristics of Askin's tumor.
